WebF1 generation phenotypes ≈ 50% white ≈ 50% yellow F1 generation genotypes W? ww Since there are recessive offspring, the white parent must have carried the recessive allele and therefore had the heterozygous genotype, Ww. As a check, a cross of Ww x ww produces 50% white and 50% yellow in the F1 generation. 3. WebDec 18, 2024 · What is the definition of a genotype? In biology, a gene is a section of DNA that encodes a trait. The precise arrangement of nucleotides (each composed of a phosphate group, sugar and a base) in a gene can differ between copies of the same gene. Therefore, a gene can exist in different forms across organisms.
